Sparky Builder is run by one person and an AI. Most questions are answered below. There is no SLA, no phone number and no guaranteed response — if the answer isn't here, send a message and a real human (Chris) reads it when he can.
You tell an AI on your phone what app you want, in plain words. It writes real source code, compiles it, and hands you an installable Android app you own. No coding at any point. The building happens on a computer you own — see the setup guide for exactly what that means.
Yes. The source code and the app are yours to keep, change, and use. You're also responsible for them — see our Terms.
Free-ish. We charge nothing and there is no paid tier. Your costs are a Claude subscription or API key (around $20/month, paid to Anthropic — never to us) and a computer you're willing to leave switched on. We don't host anything for you and we never see your key.
You do. A real Android app has to be compiled, and phones can't do that themselves. Any always-on Windows, Mac or Linux machine works — an old laptop in a cupboard is plenty. You set it up once and never touch it again; after that the phone is the only thing you use. The trade you get for that hassle is that nothing of yours runs on our machine, so nobody can meter you, bill you later, or switch you off.
Usually one of three things: the phone is on mobile data instead of your wi-fi, the computer has gone to sleep, or your router handed the computer a new address. The setup guide has the full checklist at the bottom.
AI-generated code can contain bugs or security issues. Always review and test before relying on or sharing an app. We don't review or guarantee generated code.
There's no gate any more. Go straight to the setup guide and start — or drop your email on the main page and it gets sent to you.

Before you write: most problems are setup problems, and the setup guide has a troubleshooting section that covers nearly all of them.
